Application filed Ju1y 15, 1320. serialNo. 396,580.

T 0 all whom 2 2? may concern:

Be it known that we, Gnonen W. Goss, CHARLES E. Gross, and CHARLES 0.Bowen,

citizens of the United States, residing at.

Baltimore, in the county of F airfield and State of Ohio, have inventedcertain new and useful Improvements in Fuel Tanks, of which thefollowing is a specification.

This invention relates to improvements in the fuel tanks of motor drivenvehicles and has for its primary object to provide a fuel tank whereinis provided main and emergencytanks, the emergency tank being removablypositioned within the main tank and so located with respect to thefilling opening of the tankthat fuel will first fill the emergency tankbefore gaining access to the main tank, a construction being thereforeprovided which enables the tank structure to carry at all times areserve amount of fuel, which may be used for emergency purposes whenthe contents of the main tank have been fully drawn off. either throughaccidental, negligence or other causes.

For a further understanding of the invention, reference is to be had tothe following description and to the accompanying drawing, in whichsimilar characters of reference denote like and corresponding partsthroughout the several views thereof.

In said drawing:

Figure 1 is a vertical sectional view taken through the improved fueltank structure comprising the preferred form of the present invention. o

igure 2 is a top plan view thereof, and,

Figure 3 is a detailed perspective view of the emergency tank.

Referring more particularly to the form of the invention disclosed inthe accompanying drawing, the numeral 1 designates the improved tankstructure comprising the present invention'in its entirety. This tankstructure is formed to comprise a main outer tank 2, which may be formedfrom any suitable materials and of. any desiredproportion,as will beclearly understood. The upper portion of the tank 2 is provided with anopening 3, in which is inserted and suitably secured a ring or collar 4,which latter serves to reinforce the edges of the opening 3 and torender the construction of the tank 2 at portions surrounding theopening 3 of substantial and strong construction. V 7

Threaded into the collar 4: as at 5 is a metallic. plate member 6, whichhas its upper surface arranged to terminate substantially evenly withthe upper surface of the collar 4-, and furthermore, said plate memberis provided with .a plurality of fingers 7, by means of whichitsthreaded rotation into. andj-oujt of thercollar 4 is facilitated. Inthis instance, the plate' member is'provid'edto one side thereof with athreaded. opening v8, in which is removably IIEEE. c

received a similarly threaded filling cap or plug 9, which is adapted tonormally cover the fuel entrance of the tankstructure. The under side ofthe plate member 6 is provided with'a flange 10, to which is suitablysecured the upper annular edge 11 of an emergency tank 12.

This tank may be of any suitablev size and construction and is of suchproportion as to be capable of being withdrawn from the tank 2 by way ofthe opening 3 provided in the latter. It will be observedthat the tank12 is situated in depending relationship with respect to-the platemember 6, and by being connected with the latter said emergency tankwill normally occupy a suspended position within the tank 2. Moreover,the tank 12 is provided with an open upper end which is adapted to besituated immediately beneath the filling opening 8, so that'fuel to beplaced within the tank 2 must first'be'received withinthe emergencytank, a feature which insures the required reserve amount of fuel withinthe tank 12 in a manner independent substantially of the main tank. Theupper edge 11 of the emergency tank is provided with an opening orrecess 13, which is so situated that when the tank 12 has been filled,fluid placed therein will overflow by way of the'opening 13 and willthen be discharged into the main tank, permitting of the filling of thelatter. I

In operation, fuel is withdrawn from the main tank by way of the usualoutlet. connection 14 provided in the base of the tank and-should ithappen during the operation of an associated vehicle, that the contentsofthe main tank should become. exhausted either by virtue offorgetfulness or other accidental reasons, the supplyof fuel may bereplenished by the fuel within the emergency tank. Use of this latterfuel may be brought about by removing the plate member 6 and itsassociated, emergency tank from their applied positions in connectionwith the collar 4. When so removed, the emergency tank is positionedimmediately above the opening 8 and is inverted so that its contents maydrain out of the opening 13 and deposited Within the main tank, thuspermitting the fuel to be utilized in the ordinary manner. After thefuel has been drained from the emergency tank, the latter together withits plate member 6 are again positioned in engagement With the collar l,and the vehicle may then continue until the tank 2 is again replenishedwith fuel. gency tank may be of any desired proportion, but the sameshould receive a suiiicient amount of fuel to operate the motor of thevehicle for a considerable period of time. It will be observed that byreason or" the location of the reserve or emergency tank, it Will beimpossible to fill the main tank Without first filling said reservetank. This provides a feature which insures the complete filling of thetank 12 in sub stantially automatic manner and Without involvlng thenecessity oi relying upon the memory of the vehicle operator, ifdesired, the lower edge of the opening 13 may be provided with aninwardly directed flange 15, which serves to confine the contents of thetank 12, and prevents the fuel of the latter from being jostled out ofthe opening 13 during the operation of the vehicle. Also, one side ofthe tank 12 is preterably indented as at 16, which indented portion isadapted to register with one side or the filling opening 8, whereby uponthe removal of the cap 9., a sage stick or the like may be inserted intothe main tank for the purpose of denoting the fuel level of the, latter.The level of the fuel in the main tankmay therefore be denoted by themere removal of the cap 9, a feature Which does away with the necessityor removing the platev member 6 and the associated reserve tank for morefuel level determining purposes. a

In view 01"? the foregoing description, taken in connection'with theaccompanying drawing, it Will be manifest that the invention provides asimple and useful structure of a substantially automatic nature whichwill overcome the annoyance and inc0n venience due to accidentalexhaustion oi"- the contents of a fuel tank. The location of theemergency tank is such that the reserve supply of fuel may be readilyobtained, which Will be suthcient under ordinary circumstances tosupplythe needs of an asso 'ciated motor until the main tank may againbe fully replenished. The invention is also it Will be understood thatthe emer' considerably reduces the costof manufacand installation of theinvention. it is not claimed that the present invention broadly coversthe idea of providing an fuel tank vi in a main -l k, out that saidinvention is defined and the following the scope thereof indicated byms. hat is claimed is: l.
